Working principle: Kaidun Non- pressure Solar Water Heater is a simple form of making use of solar energy to get hot water. It directly joints the heat collector with the water tank on the top. There is no need of pump to push the water and no need of pipeline between the collectors and the tank. When the water in the vacuum heat-collecting tube is heated, its density will decrease and will go upward into the tank; meanwhile the cold water in the tank will flow down into the tube due to its greater[...]

Split Pressurized System Split pressurized solar water heater is composed of heat pipe, evacuated tube solar collector, pump station (including circulation pump, controller, expansion vessel, pressure gauge, sensors etc) and pressurized water tank. Working principle: When the temperature of the heat collector reaches the set value, the controller shall start the circulation pump automatically. The circulation pump makes heat-conducting liquid circulate automatically. The heat-conducting liquid[...]
